Question

What is the maximum value of an ac voltage whose RMS value is 100 V?

Short answer

The maximum value of an ac voltage is 141 V.

Step-by-step solution

Listing the given quantities:

${\mathrm{V}}_{\mathrm{rms}}=100\mathrm{V}$

Understanding the concepts of rms value:

The value of maximum voltage can be found from itsrms value using the corresponding relation.

Calculation of the maximum voltage:

To find maximum voltage:

$\begin{array}{rcl}{\mathrm{V}}_{\max }& =& \sqrt{2}{\mathrm{V}}_{\mathrm{rms}}\\ & =& \sqrt{2}\times 100\\ & =& 141\mathrm{V}\end{array}$

Hence, the maximum value of an ac voltage is data-custom-editor="chemistry" $141\mathrm{V}$.
